Impact 2026-03-21 6 min read
TL;DR

A naval war in the Persian Gulf could lead to the closure of the Strait of Hormuz, causing a global economic crisis. Iran's anti-ship missiles, mines, and submarines pose a significant threat to US Navy carrier strike groups and Gulf state navies.

Overview

The Strait of Hormuz is a critical waterway, with 20% of global oil passing through it, worth $1.3 billion daily. A closure would lead to a significant increase in oil prices, with estimates suggesting a 20-30% rise. This would have far-reaching consequences for the global economy, including increased inflation, reduced economic growth, and potential recession. The US Navy and Gulf state navies are taking steps to mitigate the threat, including increased patrols and military exercises. However, Iran's naval capabilities, including its anti-ship missiles, mines, and submarines, pose a significant challenge.
